Mojo trait

TileLoader

Base trait for tile loading mechanisms in matrix multiplication.

This trait defines the interface for loading tiles from global memory to shared memory, abstracting over different hardware mechanisms.

comptime members

__copyinit__is_trivial

comptime __copyinit__is_trivial

A flag (often compiler generated) to indicate whether the implementation of __copyinit__ is trivial.

The implementation of __copyinit__ is considered to be trivial if:

  • The struct has a compiler-generated trivial __copyinit__ and all its fields have a trivial __copyinit__ method.

In practice, it means the value can be copied by copying the bits from one location to another without side effects.

__del__is_trivial

comptime __del__is_trivial

A flag (often compiler generated) to indicate whether the implementation of __del__ is trivial.

The implementation of __del__ is considered to be trivial if:

  • The struct has a compiler-generated trivial destructor and all its fields have a trivial __del__ method.

In practice, it means that the __del__ can be considered as no-op.

__moveinit__is_trivial

comptime __moveinit__is_trivial

A flag (often compiler generated) to indicate whether the implementation of __moveinit__ is trivial.

The implementation of __moveinit__ is considered to be trivial if:

  • The struct has a compiler-generated __moveinit__ and all its fields have a trivial __moveinit__ method.

In practice, it means the value can be moved by moving the bits from one location to another without side effects.

Required methods

__copyinit__

__copyinit__(out self: _Self, existing: _Self, /)

Create a new instance of the value by copying an existing one.

Args:

  • existing (_Self): The value to copy.

Returns:

_Self

__moveinit__

__moveinit__(out self: _Self, deinit existing: _Self, /)

Create a new instance of the value by moving the value of another.

Args:

  • existing (_Self): The value to move.

Returns:

_Self

load_tile

load_tile(self: _Self, dst: LayoutTensor[_Self._dtype, layout, MutAnyOrigin, address_space=AddressSpace.SHARED, element_layout=element_layout, layout_int_type=layout_int_type, linear_idx_type=linear_idx_type, masked=masked, alignment=128], mem_barrier: LegacyUnsafePointer[SharedMemBarrier, address_space=AddressSpace.SHARED], coords: Tuple[UInt, UInt])

Load a tile from global memory to shared memory.

Args:

  • dst (LayoutTensor): Destination tile in shared memory (must be 128-byte aligned).
  • mem_barrier (LegacyUnsafePointer): Memory barrier for synchronization.
  • coords (Tuple): Tile coordinates (row, column) in the source matrix.

Provided methods

copy

copy(self: _Self) -> _Self

Explicitly construct a copy of self.

Returns:

_Self: A copy of this value.
